This last point is the part that confused me the most. I assumed that
you had to simulate throwing the pen, but for this simulation you need Pi,
but since you're trying to compute pi, presumably you don't know Pi yet!

It did not occur to me that perhaps the assignment was to throw the pen
in real life, and then write a computer program that kept track of how many
line-crosses you got, and approximate Pi that way.

I'm also not sure where the "64 processors" part comes into play, unless
this is actually an assignment on parallel programming.
